SHY TRICK
Prerequisite for this trick is a paw target touch and stay.
For many dogs they are going to learn this trick originally easiest from a down position or a sit, play a little with each to see which your dog seems more naturally paw agile with (for example Nick learned this much easier from a down because he has big long legs and is naturally very flexible, Emily has shorter legs and had more flexibility if she was sitting so she could use more shoulder.
First start by teaching your dog to touch a target with their paw.
Work to where they will target a small piece of paper, with their paw touch.
Work on moving the target around with the dog in either a sit or down and having them reach for the paper target without leaving that position.
When they can reach the target at a position above their nose while maintaining a sit or down then use either a post it note for your target or use a small piece of tape to put the target on their muzzle.
Each dog has a magic whisker tickle spot that will have them swat at the target.
Click when their paw makes contact with the target.
When you reward do so with their head close to where it needs to be when they hold the position, so don’t reward in a position that raises their heads back up, they will need to maintain a nose down position to hold the shy.
For some dogs you can reverse target if they struggle with the paw on the nose, this means you use a nose target and get them to target their nose under their paw.
